近年来,有限元法已在结构分析中得到广泛的应用,并收到了很好的效果。本文结合桥梁墩台桩(柱)基础的结构特点,介绍一种用有限元法进行空间计算的方法。文中采用位移法,即把节点的位移(每节点包括三个线位移和三个转角)作为基本未知数来求解。该法的特点是:把多种不同的桩(柱)基础杆件型式统一摸拟成一种模式,建立起一个一节点(六个自由度)单元刚
In recent years, the finite element method has been widely used in structural analysis, and received good results. In this paper, based on the structural characteristics of bridge piers and piles (columns) foundation, this paper introduces a method of space calculation using finite element method. In this paper, the displacement method, that is, the node’s displacement (each node includes three line displacement and three corners) as the basic unknown to solve. The law is characterized by: a variety of different types of piles (pillars) basic pieces of a unified simulation into a model, the establishment of a node (six degrees of freedom)
